All parts are used.

I have some parts left over from troubleshooting my issue. The computer would work, then stop. Then sometimes work. (turned out to be bad grounds)

A number of 16197427 computers. $25 ea. (1994/1995 GM)
An engine harness cut for a IH (no transmission control wires!) The only issue is the ground eyes are broken/missing. $80
IAC, $10
HEI spark coil $10
Ignition control module (for the above computers) $10

Add USPS Flat rate $6 for one part or $12 for more than one part.
